Universidad glacier LANDSAT 8 analysis results

The files in this dataset are LANDSAT 8 images and maps of parameters derived from these images. Four sets of maps are included, each covering time period between 2013 and 2022: - LANDSAT 8 multispectral image sourced from the Google Earth Engine API - Albedo map computed from this image with a formula of () - GRAI map computed from this image with a formula included in the project's final publication (Podgorski et al 2023) - Debris abundance map derived from the GRAI map The maps show the state of the glacier's surface at the end of the ablation season in each year (end of March/beginning of April).
